Massively parallel genome engineering followed by pooled growth selections for rapid target discovery in microbes

The ability to engineer the entire genome of microorganisms at a massively parallel scale using the Onyx platform will reshape the manner in which researchers perform pooled cultivation experiments (such as ALE) and generate data sets. Here, Onyx technology was used to rapidly generate genomewide k... More


Rebuilding evolutionary success: Using Inscripta’s Onyx Digital Genome Engineering Platform to ease and enhance Adaptive Laboratory Evolution experiments

Adaptive Laboratory Evolution (ALE) is a powerful approach to leverage biology’s evolutionary capacity to develop strains that thrive in challenging growth environments, with applications to biotechnology and bioproduction and for basic biochemical discovery. ALE experiments have been enabled by nex... More


Enrichment of transfected cells with Dharmacon Edit-R Fluorescent dCas9-VPR mRNA

Edit-R Fluorescent dCas9-VPR mRNA enables both transfection optimization and enrichment for gene modulation experiments. For optimal enrichment of edited cells, sorting the cells for high EGFP expression levels (selecting the top 10% fluorescence) in addition to negative and dim fluorescence for com... More


CRISPRmod dCas9-VPR or dCas9- SALL1-SDS3 mRNA and synthetic guide RNA transfection protocol

The following is a protocol for transfecting CRISPRmod dCas9-VPR or dCas9-SALL1-SDS3 mRNA with synthetic guide RNA into cultured mammalian cells using DharmaFECT™ Duo transfection reagent (Cat #T-2010-xx). The protocol is written for transfection into 96-well tissue culture plates.... More


Detect Specific Protein Aggregates in Biologic Formulations with the Aura Immunoassay

Biologic co-formulations target multiple pharmacologically active sites to increase therapy efficacy. However, either biologic can be a source of protein aggregation that can negatively influence the product’s safety, efficacy, and therapy. Aura systems are the only particle analyzer that can pinpoi... More
